Joseph Studer Stéphanie Baggio Meichun Mohler-Kuo Olivier Simon Jean-Bernard Daeppen Gerhard Gmel 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2016,32(2):421-440
The study aimed to identify different patterns of gambling activities (PGAs) and to investigate how PGAs differed in gambling problems, substance use outcomes, personality traits and coping strategies. A representative sample of 4989 young Swiss males completed a questionnaire assessing seven distinct gambling activities, gambling problems, substance use outcomes, personality traits and coping strategies. PGAs were identified using latent class analysis (LCA). Differences between PGAs in gambling and substance use outcomes, personality traits and coping strategies were tested. LCA identified six different PGAs. With regard to gambling and substance use outcomes, the three most problematic PGAs were extensive gamblers, followed by private gamblers, and electronic lottery and casino gamblers, respectively. By contrast, the three least detrimental PGAs were rare or non-gamblers, lottery only gamblers and casino gamblers. With regard to personality traits, compared with rare or non-gamblers, private and casino gamblers reported higher levels of sensation seeking. Electronic lottery and casino gamblers, private gamblers and extensive gamblers had higher levels of aggression-hostility. Extensive and casino gamblers reported higher levels of sociability, whereas casino gamblers reported lower levels of anxiety–neuroticism. Extensive gamblers used more maladaptive and less adaptive coping strategies than other groups. Results suggest that gambling is not a homogeneous activity since different types of gamblers exist according to the PGA they are engaged in. Extensive gamblers, electronic and casino gamblers and private gamblers may have the most problematic PGAs. Personality traits and coping skills may predispose individuals to PGAs associated with more or less negative outcomes. 相似文献

Constructed wetlands in urban environments may be used by urban amphibian populations for breeding. Yet, few studies have examined the performance of young-of-the-year from created wetlands even though the success of terrestrial life stages is directly linked to the performance of individuals at the egg and larval stage. We assessed how early-stage amphibians developing within constructed stormwater wetlands compared in body size (one metric of performance) to those in nearby natural wetlands. We conducted surveys for wood frog, Lithobates sylvaticus, larvae and young-of-the-year metamorphs at 13 wetlands located in the City of Edmonton, Alberta, Canada and compared metamorph size (a useful metric for fitness and reproductive success) between constructed stormwater and two types of natural wetlands. We related body size to within-wetland parameters (reflecting water chemistry, thermal regimes and physical characteristics) and used an information-theoretic approach to identify predictors of metamorph body size. Abundances of egg masses, larvae and metamorphs were generally lower at stormwater than natural wetlands. Metamorphs exhibited larger body size in stormwater wetlands compared to natural wetlands. Low metamorph abundances and cool, stable water temperatures best explained large body size in stormwater metamorphs. We propose that with increasing urbanization and associated construction of artificial wetlands, size benefits in early developmental stages may help individuals cope with reduced habitat suitability in the terrestrial environment. 相似文献

Promoting Financial Capability of Incarcerated Women for Community Reentry: A Call to Social Workers
Cynthia K. Sanders 《Journal of Community Practice》2016,24(4):389-409
ABSTRACTFemale incarceration rates are increasing at unprecedented rates. The majority of women are poor single mothers, serving sentences for nonviolent drug-related and property offenses. Among challenges faced when transitioning back into society are a history of interpersonal violence and financial instability. This study examines literature with regard to the barriers women experience with an emphasis on financial struggles and explores outcomes of one initiative to begin addressing the financial capability of women in a minimum security prison. Findings reveal women benefited from the class experience. Social workers are called upon for additional financial capability programming and research in this area. 相似文献

The socio-ecological challenges facing communities in the 21st century are building towards a critical conjuncture of history, culture, power, and profound inequity. Scholars working in the service of social transformation and improving the wellbeing of communities are calling for creative, deliberate, and consequential interventions. Tharp & O’Donnell (this issue) call for increased engagement between Cultural-Community Psychology and Cultural-Historical Activity Theory to lead this kind of call. Drawing from our experiences in community based design research, we argue for cultivating axiological innovations in research and interventions. We explore three examples including: critical historicity, inter-generational learning, and strategic transformations of institutional relations. 相似文献

The current study examines how the horror-based AMC television series The Walking Dead portrays religion in terms of a reframing of the role, if any, of faith in a higher power, and the portrayal of the faithful. The religious-themed discourse of this highly successful story about survivors of a zombie apocalypse as presented through dialogic and visual imagery serves as the text analyzed here; specifically, related episodes set in churches at two separate points in the series that combine to offer a metaphor of “structure” used to disassemble and reconstruct the role of religion. These episodes interlace religious themes to develop an overarching message that forms a representative anecdote of replacement in which the notion of “faith” becomes redefined. 相似文献

This paper examines forecast error with an intention not to minimize forecast error so much as to bias the resultant error in order to achieve better managerial results. Much work has been accomplished by other researchers toward the goal of minimizing forecast error—sometimes by the use of sophisticated forecasting techniques. The results of this paper indicate that manipulating forecast error bias may be the better managerial strategy as opposed to going to great lengths to minimize forecast error. Subject Areas: Forecasting, Aggregate Planning, Capacity Planning, and Production/Operations Management. 相似文献

A probabilistic dealing strategy is proposed which allows all premium brands in an established market to earn nonnegative profits without cooperation. Following the strategy, brands take turns attracting deal-responsive customers. Relative to a reactive competitive strategy, the proposed strategy improves the positions of all premium brands. With use of the strategy, average deal sizes are positively related to a brand's market share, the proportion of quality conscious customers, the proportion of informed customers, the span of regular prices in a market, and the range of customers' acceptable prices. 相似文献

For convex and concave mathematical programs restrictive constraints (i.e., their deletion would change the optimum) will always be binding at the optimum, and vice versa. Less well-known is the fact that this property does not hold more generally, even for problems with convex feasible sets. This paper demonstrates the latter fact using numerical illustrations of common classes of problems. It then discusses the implications for public policy analysis, econometric estimation, and solution algorithms. 相似文献

In the study of risks
, different sciences use the same category in different ways, each related to its own ontological assumptions. But many of
these fields communicate very little with one another. This article seeks to approximate two of these areas of study that
have shown similar concerns and that can mutually strengthen one another, namely, geography and demography. Geography was
one of the first disciplines to include risk in its environmental dimension and has had broad experience in simultaneously
focusing on social and natural dynamics. Demography, on the other hand, faces greater difficulties because only recently has
it incorporated the environmental dimension into its scientific scope. Both have brought the concept of vulnerability into
their conceptual framework as complementary to that of risk. Geographers understand vulnerability as a more symbiotic form
of the relationship between society and nature, whereas demographers give it a strong socioeconomic component. In this regard,
the conceptual discussion on risks and vulnerabilities, in its attempt at approximating these two fields, is a way of conceptually
advancing and strengthening the different approaches to empirical work, especially in population–environment studies which
is the common ground for the dialogue between the two disciplines.
